Welcome to O'Brien Constructors

We are a general contractor based in Portland, Oregon that specializes in projects with high client involvement and design team integration. Our workload includes a mix of hard bid and alternative delivery method projects, such as design/build, construction manager/general contractor, and guaranteed maximum price, for both the public and private sectors.

In the field, we have a core group of five superintendents that have all been with the company five or more years. Their skills and abilities allow us to be confident that our self-performed work meets the high standards our clients demand.

At O'Brien Constructors, we approach every project as a relationship; and we look forward to building relationships for years to come.
